Male is similar to P. lacustris by (a) ocurring at streams, rivers and lakes in tropical Africa; (b) labrum pale, at most vaguely darkened at base; (c) thorax yellow to green with more prominent brown to black markings, that on metastigma ends just dorsal of it; (d) Pt brown, not contrasting with black veins; (e) S8-9 with broad foliations; (f) cerci less slender, apex blunt, without or with one tooth; (g) cerci without distinct ventral ridge; epiproct about 1/3 as long as cerci. However, differs by (1) relatively larger size, Hw 23-27 mm; (2) dark markings sharp, clearly delimiting pale postdorsal and antehumeral stripes; (3) cerci slender, apex rather blunt, without distinct tooth.
